Novak Djokovic continued his bid to finally win his first-ever French Open on Wednesday, beating Roberto Bautista Agut in four sets.

Andy Murray needed four sets to get past Richard Gasquet while Stan Wawrinka beat Albert Ramos Vinolas in three. The two will meet in the semi-finals, with the rest of the men's contenders still to finish their quarter-final matches.

In the women's draw, Serena Williams had little trouble getting past Elina Svitolina, but her sister, Venus Williams, lost to Timea Bacsinszky in straight sets.

Djokovic resumed his match against Agut in the third set after rain delays forced the contest to be suspended earlier, and if the Serb looked vulnerable in the past few days, those struggles were gone on Wednesday.

The world No. 1 looked calm and relaxed playing from the baseline and attacked the net with a little more aggression, frequently putting his opponent in awkward positions.

As shared by the event's official Twitter account, Djokovic's relaxed demeanor showed in his post-match celebrations:

Per Eurosport UK, he kept up the shenanigans in his post-match interview:

It's good to see Djokovic having fun on the court, and his laid-back approach appears to be working. With the likes of Roger Federer and Rafael Nadal no longer in Paris, the road to his first Roland Garros win appears wide open. He'll meet Thomas Berdych in the next round.

Murray overcame some sloppy play to qualify for the semi-finals, beating Gasquet in four sets. The Scot served for the first set up 5-3 before losing four games in a row and then recovered from a 3-1 deficit in the tie-break to start his rally.

His play improved dramatically in the third and fourth set, as he dominated the rallies and scored several spectacular points with his backhand. Murray showed the form he'll need to get past defending champion Wawrinka and book his first-ever Roland Garros final ticket.

Wawrinka needed just three sets to get past clay specialist Ramos, who was overwhelmed by the attacking brilliance of his Swiss opponent early but turned the final set into a real battle. Ramos did some damage from the baseline and impressed with his defensive ability, perhaps showing Murray the blueprint to beat the reigning champion.

David Goffin beat Ernests Gulbis in four sets to advance to the quarter-finals, while Dominic Thiem worked his way past Marcel Granollers.

Defending champion Williams needed just over an hour to power through to the quarter-finals, giving Svitolina just two games in a quick win.

The women's favourite wasted no time, powering home winner after winner from the baseline and using clean groundstrokes and her serve to get on the front foot. Per BBC Tennis, the American took care of business:

Similar to the men's draw, the women's draw has already lost its fair share of title favourites, and at this point, it seems no one will be able to get the better of Williams, unless she has a bad day.

One major obstacle could be the schedule, however. Due to the numerous rain delays, the French Open organisers find themselves in a bit of a pickle. Per Christopher Clarey of the New York Times, Williams made it clear she would be fine with playing on a daily basis moving forward:

#Serena says she would have no problem playing 4 singles matches in 4 days but would draw line at playing twice in singles in one day

She won't be facing her sister in this year's French Open, as the other Williams lasted just 76 minutes against Bacsinszky, losing in straight sets.

Williams broke Bacsinszky's serve early, but her Swiss opponent soon found a rhythm with her groundstrokes and forced the American into numerous unforced errors.

Per Clarey, she later said the wet clay had an effect on her play:
